Max Days Get a FREE Estimate on a new AC system

With 40 years of experience as a company, we’ve built a top-notch team of technicians with the expertise to thoroughly evaluate your needs and recommend the right AC unit for you. A new air conditioning system installation can be a significant expense, so we ensure that you get the best value for your money without compromising on quality.

McGowan’s is a factory-authorized dealer for American-made Carrier air conditioners. We specialize in the installation and service of Carrier air conditioners and heat pumps, and are able to pass along special savings on Carrier products to our customers. In 2012, we earned the Carrier President’s Award, the company’s highest honor for its leading dealers.

When you’re ready for a quote on a new AC unit, call us for a free estimate. We’ll get to know your comfort requirements, perform an air-flow analysis and check the load on your system. Once our tests are complete, we’ll review your equipment options and any current promotions that may be available, and provide you our company license and insurance documents.

We know how important our customers’ comfort is, especially during the hot summer months in the St. Augustine area. That’s why we respond quickly when your air conditioner or heat pump isn’t working at peak efficiency.

St. Augustine AC Duct Cleaning Service

If you or your family members suffer from asthma, allergies or other respiratory conditions, did you know that the cleanliness of your air ducts may be a contributing to factor to aggravating symptoms of these conditions? Indoor air quality is one of McGowan’s specialties, and our duct cleaning service is a good way to ensure that the accumulation of dust or the growth of mold isn’t causing problems in your home.

In addition to the potential health benefits, air duct cleaning of your St. Augustine home or business improves the efficiency of your entire system. Recirculating particulates such as pollen and dust throughout your system can compromise your AC unit’s performance, potentially leading to higher energy bills. McGowan’s duct cleaning service includes the inspection of every component of your system, and clean not only your air ducts but also your coils, heat exchangers and other parts of your air conditioning system.
